[0028] Wherein, the preparation method of the arbuscular mycorrhizal agent comprises: cultivating arbuscular mycorrhizal fungi, corn and clover in a propagation substrate to obtain the arbuscular mycorrhizal agent.
[0029] Wherein, the inoculum quality of the arbuscular mycorrhizal agent is 3-5% of the mass of the propagation matrix;
[0030] Wherein, each gram of the arbuscular mycorrhizal fungal agent contains 50-80 arbuscular mycorrhizal fungal spores.
[0031] Wherein, the species of the rhizobia bacterial agent include but not limited to any one of the mesobrady-growing Rhizobium tianshani and Sinorhizobium fischeri.
[0032] Wherein, the preparation method of described rhizobia bacterial agent comprises:
[0033] The rhizobia strains were shaken in the culture medium, and the bacteria were collected after centrifugation and redissolved in 8-12mmol / LMgSO 4 .7H 2 O as the inoculum;
[0034] Wherein, the number of effective viable bacteria in the inoculum>2×10 10 cfu / ...
Embodiment 1
[0049] Configure licorice-specific bio-organic compound fertilizer, which consists of the following components by volume: 85 parts of biogas residue obtained from anaerobic fermentation, 3 parts of heavy superphosphate, 10 parts of arbuscular mycorrhizal agent and specific licorice rhizobium Bacteria agent 2 parts. Biogas residue is obtained after dehydration by a filter press, crushed and passed through a 2mm sieve, the organic matter content is 61%, and the total nitrogen content is 915mg / kg. The arbuscular mycorrhizal fungus is Rhizophagus irregularis AH01, and the inoculant is a mixture containing 78 spores / g dry soil, irregular hyphae and infected root segments. Mesorhizobium tianshanense CCBAU3306 was shaken in TY culture medium at 28°C and 125rpm for 20h, centrifuged at 3500rpm for 10min to collect the bacteria and redissolved in 10mmol / L MgSO 4 .7H 2 O was used as the inoculum, and the effective number of viable bacteria was 5.7×10 10 cfu / g.

Embodiment 2
[0054] Configure the special bio-organic compound fertilizer for licorice, which consists of the following components in parts by volume: 85 parts of biogas residue obtained from anaerobic fermentation, 3 parts of heavy superphosphate, 10 parts of broad-spectrum arbuscular mycorrhizal agent and specificity 2 parts of licorice rhizobia inoculum. Biogas residue is obtained after dehydration by a filter press, crushed and passed through a 2mm sieve, the organic matter content is 61%, and the total nitrogen content is 915mg / kg. The arbuscular mycorrhizal fungus is Rhizophagus irregularis AH01, and the inoculant is a mixture containing 78 spores / g dry soil, extraroot hyphae and infected root segments. Mesorhizobium tianshanense CCBAU3306 was cultured in TY medium at 28°C, shaken at 125rpm for 20h, centrifuged at 3500rpm for 10min to collect the bacteria and redissolved in 10mmol / L MgSO 4 .7H 2 O was used as the inoculum, and the effective number of viable bacteria was 5.7×10 10 ...
